Project Details:
Suboptimal availability and quality of drinking water as well as a lack of hygiene in water pipes on pig farms can cause animal welfare and health problems. Insufficient water intake due to technical deficiencies, low palatability due to e.g. biofilm formation in the pipes or a restrictive water supply represent a massive stressor for animals and can lead to health impairments that promote other diseases (e.g. ear and tail injuries, diarrhea).
In this project, a new drinking water pipe cleaning concept for piglet rearing farms will be established and tested for practical use in two rearing barns. The system, developed in a collaborative project and tested under laboratory conditions, will be used to clean water pipes contaminated with plaque, to destroy Salmonella reservoirs in the pipes, and to reduce endotoxin contamination. It is exspected, that ear and tail lesions will be reduced after cleaning the drinking water pipes in case that they are related to endotoxins. After technical, chemical and microbiological analyses, as well as examinations of the piglets, the drinking water pipe cleaning is carried out on the farms. A newly developed mobile flushing device and a new substance containing tartaric acid and catalytic additives are used. The substance is highly effective against biofilms and also destroys the genetic material of pathogens. The effects of this cleaning concept will be measured and evaluated on two farms in three baches respectively.

Solanum glaucophyllum (waxy nightshade) is one of the few plants that naturally produces 1,25-dihydroxycholecalciferol glycosides (1,25(OH)2D3-gly). In the literature it is mentioned that the glycosides are cleaved before absorption and thus only the aglycone is absorbed. However, no data are known so far that confirm this assumption analytically. In a multi-stage approach, this question is to be clarified in vitro. To do this, a number of preliminary tests must first be carried out, including one focusing on possible cell toxicity. Since the cell toxicity of 1,25(OH)2D3-gly can only be extrapolated from the data for synthetic 1,25(OH)2D3 to a limited extent, this experiment serves to determine the maximum possible dose.

Basis_SOUVER@N supports the joint project SOUVER@N through accompanying measures. The project aims to strengthen the cooperation of experts and to identify the heterogeneous technical and organizational framework conditions of the universities participating in the SOUVER@N joint project and to promote their compatibility.

Results:

An der Stiftung Tierärztliche Hochschule (TiHo) wurden im Rahmen des Verbundprojektes u.a. technische Voraussetzungen für die digitale Lehre erweitert sowie Dozierende beim digitalen Lehren und Studierende beim digitalen Lernen unterstützt. Anleitungen zur digitalen Lehre und zu digitalen Lerntechnologien wurden neu erstellt oder überarbeitet. Für Studierende wurde ein neues virtuelles Mikroskop für das Selbststudium geschaffen. Lehrveranstaltungsräume wurden mit Technik für die hybride Lehre bzw. für Vorlesungsaufzeichnungen ausgestattet, das Lernmanagementsystem Moodle, welches an der TiHo eingesetzt wird, wurde erweitert.

Project Details:
Early detection of individuals with a SARS-CoV-2 infection remains the most important tool to interrupt the chain of infection. Several studies have already proven canines? extraordinary olfactory acuity to detect SARS-CoV-2-infected individuals. However, with increasing knowledge about the virus, the variety and chronicity of the disease expression and an increase in the number of people that are vaccinated, some questions have not yet been answered. We will test a variety of hypotheses to further explore the use of detection dogs as a screening method for SARS-CoV-2-infections.

Results:

Dogs can distinguish SARS-CoV-2-infections from other viral infections. However, compared to earlier studies our scent dogs achieved lower diagnostic sensitivities. To deploy COVID-19 detection dogs as a reliable screening method it is therefore mandatory to include a variety of samples from different viral respiratory tract infections in dog training to ensure a successful discrimination process.

Auf das Coronavirus trainierte Spürhunde werden in diesem Herbst bei mehreren Musikveranstaltungen eingesetzt und mit Antigen- und rtRT-PCR-Tests verglichen. Dies wird weitere Erkenntnisse darüber liefern, wie Corona-Spürhunde am besten bei der Detektion infizierten Menschen eingesetzt werden können.

Project Details:
The aim of this study is to determine the sound level in pigs' nursery compartments and to detect the effects of animal behaviour and barn technology on the sound level.
In addition, occupational safety will be considered in the study by identifying particular sound events to which both, animals and humans are exposed, and quantifying them with regard to the sound pressure level. The aim is to generate representative data on noise pollution in today's piglet rearing in Germany, to determine the origin of noise pollution and - if necessary - to identify potential for improvement in terms of animal welfare and occupational safety.
